What time will it be, step by step
Given a start and how long something lasts, when does it end?
The question
4:05 + 25 min
- It starts at 4:05 and runs for 25 minutes. Hop forwards along the line rather than adding the digits — then the hour never has to be carried.
- It all fits inside the one hour, so it is a single hop of 25 minutes — no o'clock to cross.
- So it ends at 4:30.
